Promotion of Smart Street Light Pole - Technical Guidance - solar street light-litersola

It is learned from the Provincial Science Information Center, the promotion unit of the financial subsidy for energy-saving light cannons, that the focus of promotion this month will shift from community residents to bulk users. It is understood that some financial subsidy energy-saving lamps promotion plans for community residents and users have been completed ahead of schedule. According to the plan, the first batch of government subsidies to promote energy-saving lamps will end at the end of this month. Enterprises can buy energy-saving lamps at half price It is understood that bulk users refer to industrial and mining enterprises, office buildings, hospitals, schools, hotels, commercial buildings, stations, airports, docks, roads and other places where lighting products are concentrated. Relevant departments of our province have issued documents to various district and county-level economic and trade departments and some municipal enterprises to encourage the purchase of high-efficiency lighting products. According to reports, the central government subsidizes each high-efficiency lighting product by 30% of the supply price in the winning bid agreement, and the actual purchase price of bulk users is less than half of the market price. Zhang Kaiming, sales manager of Foshan Electric, explained that the retail price of a T5 bracket 14W energy-saving lamp is more than 40 yuan. After government subsidies, bulk users only need to pay 17.5 yuan. Zheng Wenfeng, director of the Provincial Science Information Center, told reporters that compared with the high enthusiasm of citizens to buy, the bulk users are a bit 'cold'. It is understood that, taking Guangzhou as an example, so far only 100,000 pieces of promotion tasks have been completed for bulk users, and there are still 300,000 pieces, mainly T8 tri-color fluorescent lamps and T5 bracket integrated fluorescent lamps. Zhang Kaiming told reporters that the promotion effect of bulk users in other provinces is also not good. At present, most provinces have only completed about 30%. The promotion of subsidized lamps is not a commercial act. Compared with the high enthusiasm of citizens to purchase, why are large-scale users a little 'cold' to financially subsidized energy-saving lamps? In this regard, the author interviewed more than ten large enterprises and institutions, most of which expressed their concern for energy-saving lamps. The lamp promotion project is very interested, and some are already planning the energy-saving lamp renovation project, but many units still have various concerns. A relevant person in charge of a large hospital said that they are currently skeptical about whether energy-saving lamps are really energy-saving. However, many units have not been able to introduce energy-saving lamps, not because they do not agree with the project itself, but because each unit has a budget for the expenditure of large expenses. The replacement of energy-saving lamps is not as simple as replacing two lamps in ordinary families. So it takes a long time to consider. In addition, the author interviewed relevant enterprises and promotion units and found that in the promotion process for bulk users, the connection between enterprises and promotion departments was insufficient, resulting in poor promotion effects. Some units did not even know that they could buy low-cost energy-saving lamps subsidized by the government. . Zheng Wenfeng has repeatedly emphasized that the ultimate beneficiaries of government subsidies for high-efficiency lighting products are still bulk users and urban and rural residents. This is not an ordinary commercial behavior. 'Intelligence' is no longer an unfamiliar word in people's lives, and people have increasingly relied on 'intelligence' in their lives. 'Let the city light up' advocated in recent years has led to the rapid growth of street light poles across the country. At the same time, the energy resources are facing a shortage. At present, the electricity consumed by lighting in my country accounts for about 15% of the total electricity production. Under various pressures, the promotion of smart street light poles is determined to win. Nowadays, many places have begun to promote the use of intelligent street light poles. Jiangxi Anfu has invested special funds to introduce a set of intelligent management and control systems for street light poles in the city. The system uses multimedia technology and computer communication technology. It can save management costs and improve work efficiency. It has been estimated that 240 street light poles can save 600 kWh per day, effectively reducing gas emissions and energy consumption, and saving expenses. The street lamp pole control circuit of the intelligent street lamp pole is composed of a decoding circuit, a switch circuit and a transformer control circuit. In order to make the time-sharing control of street light poles achieve excellent energy-saving effect, in addition to considering the opening of different gear voltages according to the time period, it is also necessary to actually consider the voltage fluctuation of the grid voltage in different time periods. The power detection circuit mainly completes the data collection of the current and voltage of the street lamp pole, converts the collected signal into an analog signal that can be collected and processed by the ADC circuit, detects whether the voltage and current are overloaded, and controls the voltage of the circuit load according to this. Switch to the corresponding gear when each gear is turned on, turn off during the off period, and monitor the rest of the period. This time-sharing shifting method takes into account the energy saving during the low power consumption period while lighting, significantly improves the power consumption efficiency, prolongs the life of street light poles, and reduces management and maintenance costs.
